' sELF-oLEAiIING RAKE.

Specification of Letters Patent.

Patented Nov. 23. 1909.

Application filed May 14, 1909. Serial No. 495.865.

To all whom it may concern:

lie it known that l, FREDEIULK \Vinnnvn 'immx. a citizen of the United States of America, residing at Lawrence, in the county of Douglas and State of Kansas, have invented new and useful Improvements in Self-Cleaning Rakes. of which the follow-' mg is a specification.

his invention relates to self-cleaning rakes. and one of the principal objects of the same is to provide a 'ake having curved teeth and a cleaner plate provided with perforations and adapted to'be moved over the teeth to strip the leaves or other material from said teeth.

Another object of the invention is to provide a rake having a perforated cleaner plate for the teeth of the rake and a sliding sleeve mounted on the handle of the rake for operating the cleaner plate ateach forvard movement of'the rake.

These and other objects may be attained by means of the construction llustrated in the accompanying drawing, in which,-

Figure l is aside elevation of a rake made in accordance with my invention, the cleaner plate being shown in its normal upper position. Fig. :2 is a side elevation, showing the cleaner plate moved to its lower position to strip the material from the rake teeth. Fig. 3 is a detail section, showing the sliding sleeve. the incloscd spring and the manner of mounting the connecting rod to the rake handle. Fi l is a sectional view on the line 4-4 of Pig. 3. Fig. 5 is a perspective view of the cleaner plate, showing the rake head in dotted lines.

llcfei'i'ing to the drawing. the nmneral l designates the rake head provided with a cross lzar L and a series of hackwardly curved tc-t th I). The head l is secured to a handle -l.

'l'hc leaner consists of a plate 3 provided with a serics of perforations it through which the teeth ii of the rake project. The plate 5 is angu ar in cross section and is rovided with an upwardly extending flange (onncctcd to the cleaner plate 5 are the hackwardly extending hraccs T which at their rear ends are provided with upwardly projecting lugs h. The cleaner is pivoted to the rake head 1 by means of a pin 9 extending through the rake head and through the inner ends of the ln'accs 7.

For operating the cleaner a connecting rod 10 is pivotally mounted-between the lugs 9 upon a pin 11, said connecting rod extendt l l l l in the rakehandle. 4.

ing backward through a groove 12 formed The end of the connecting rod 10 is bent upward, as at 13, and a spiral spring 14 surrounds the handle at this point and bears at. one end against the bent end 13 of the connecting rod 10. The opposite end of the spring llhears against a collar 15 secured upon the rake handle 4. lnclosing the spring. the collar and the end of the connecting rod is a sliding sleeve It), said sleeve having a shoulder 17 which bears against the upturned end 13 of the connecting rod and against the spring ll. The end 13 of the rod 10 extends through a hole in the sleeve 16.

The operation of my invention may he briefly described as follows :-.\s the oper ator takes the rake in his hands, casting it forward, one hand remains at the end vof-fthc handle while he uses the other as a slidein a downward course during the backward pull.

The lower sliding hand cmnes in contact with the sliding sleeve It) at the end of the stroke. This sleeve is lnoved to push forward. through the. groove'l'i of the handle 4. the connecting rod 10 moving the cleaner 5 downward over the. teeth 3 of the rake.

From the foregoing it will he obvious that my rake cleaner is of simple construction. can be manufactured at ieastmahle cost. is easy to operate. and will keep the rake clean at all times.

1. A self-cleaning rake comprising a rake head, a perforated cleaner plate pivotally mounted upon. the. head. a connecting rod pivoted to the. cleaner, a spring surrounding the handle, said connecting rod hearing against the. spring, and a sliding sleeve for operating the cleaning plate. said sleeve en' circling the spring.

2. A self-cleaning rake comprising a c eaner plate provided with perforations through which the rake teeth project, said cleaner being pivoted to the rake head. a connecting rod pivotcdto the cleaner, and a sliding sleeve mounted on the handle and inclosing a spiral spring for moving the connecting rod in one direction.

In testimony whereof l allix my signature in presence of two witnesses.
